摘要:

目的 探讨微小RNA-491-5p(miR-491-5p)过表达对人鼻咽癌HONE-1细胞增殖和迁移的影响,为研究鼻咽癌的发病机制和靶向治疗提供依据。 方法 将人鼻咽癌HONE-1细胞分为对照组(转染对照质粒)和miR-491-5p组(转染miR-491-5p质粒)。采用荧光显微镜观察2组鼻咽癌HONE-1细胞转染效率,CCK-8法检测2组鼻咽癌HONE-1细胞增殖活性,Transwell小室实验检测2组鼻咽癌HONE-1细胞的迁移细胞数,实时荧光定量PCR(RT-qPCR)法检测2组鼻咽癌HONE-1细胞中波形蛋白和上皮钙黏素mRNA表达水平,Western blotting法检测2组鼻咽癌HONE-1细胞中波形蛋白和上皮钙黏素蛋白表达水平。 结果 与对照组比较,作用24、48和72 h时miR-491-5p组鼻咽癌HONE-1细胞增殖活性(t=2.832,P=0.047 3;t=4.522,P=0.001 4;t=9.308,P<0.01)和迁移细胞数(t=9.639,P<0.01)明显降低;与对照组比较,miR-491-5p组鼻咽癌HONE-1细胞中波形蛋白mRNA(t=7.535,P=0.001 7)和蛋白(t=7.219,P=0.018 7)表达水平明显降低,上皮钙黏素mRNA(t=4.88,P=0.039 5)和蛋白(t=5.754,P=0.028 9)表达水平明显升高。 结论 MiR-491-5p过表达可以抑制人鼻咽癌细胞的增殖、迁移和上皮-间质转化(EMT)。

Abstract:

Objective To discuss the effect of microRNA-491-5p(miR-491-5p) over-expression on the proliferation and migration of the human nasopharyngeal carcinoma HONE-1 cells, and to provide the evidence for the study of the pathogenesis and targeted therapy of nasopharyngeal carcinoma. Methods The human nasopharyngeal carcinoma HONE-1 cells were divided into control group (transfected with control plasmid) and miR-491-5p group (transfected with miR-491-5p plasmid). The transfection efficiencies of the HONE-1 cells in two groups were observed under fluorescence microscope; the proliferation activities of the HONE-1 cells in two groups were detected by CCK-8 assay; the number of migration HONE-1 cells in two groups were detected by Transwell chamber assay;the expression levels of Vimentin and E-cadherin mRNA in the HONE-1 cells in two groups were detected by real-time fluorescence quantitative PCR(RT-qPCR)method; the expression levels of Vimentin and E-cadherin proteins in the HONE-1 cells in two groups were detected by Western blotting method. Results Compared with control group, the proliferation activities(t=2.832, P=0.0473; t=4.522, P=0.0014; t=9.308, P<0.01) and number of migration HONE-1 cells (t=9.639, P<0.01) in miR-491-5p group at 24,48,and 72 h after treatment were significantly decreased; compared with control group, the expression levels of Vimentin mRNA (t=7.535, P=0.0017) and protein (t=7.219, P=0.0187) in the HONE-1 cells in miR-491-5p group were significantly decreased, and the expression levels of E-cadherin mRNA (t=4.88, P=0.0395) and protein (t=5.754, P=0.0289) were significantly increased. Conclusion Over-expression of miR-491-5p can inhibit the proliferation, migration, and epithelial-mesenchymal transition (EMT) of the human nasopharyngeal carcinoma cells.
